Abstract

A detector device for limiting background noise detected by a cooled infrared detector. In order to delimit the angle of view of the detector, the device comprises a reflecting deposit formed externally of the cooling device on one face of a transparent element interposed on the receiving path. The deposit can be located on the outer face of the window of the cooling device within which the detector is mounted on a cold table forming a spherical mirror. The complete assembly is optically combined so as to ensure that the radiation issuing from the detector outside the angle of view is returned to the detector.
